en opening in the top part of the protecting hood, ciosed by a screw plug 5.

rThe driving geur consists of a horizontal Shaft 6, which is provided with A crank and e. oylincrioal toothed Wheel 8, engaging a pinion 9, The said 'pinion 9 and a Worm .x-'heel 1`i are fixed to zlnorizontal shaft 7, and the seid Worin Wheel engages screw threads provided on the spindle 11 of the centrifugal drum (not-'showny The said spindle 11 is journeled in e sleeve l2, in the tower closed partof `which a ball 13 is 1ocated, Supporting the spindle 11. The top part of the Sleeve 12 forms the neck beurng 14 of the Spindle. The sleeve 12 is 10- cated et such a level in the chamber 3, that there is e space between its top end and the innertop Side of the seid chamber.

1n order to permit the sleeve 12 and the spindle 11 to osollete to a Certain extent, so that the spindle con be centered during the rotary movement of the drum, the sleeve 12 hee a swell 15 forming it. part of a sphere. i# on) the sioie Wall 'of the chamber 3 e shelf .16 projects inward and is provided with a recess 17, ,which is cup shaped in accord ence with the shape of the swell 15. '"1 sleeve 12 is iocuted with its swell 15 in the "said recess as shown. The center point of the sphere is toczrted' on a horizontal line drawn through the centernf the shaft 7 and the center of the spindle 11. Owing to the described arrangement the sleeve 12 and 'the Spindle 11 een oseiilute to some extent in :1U directions. I n order to prevent the sleeve 12 from rotating with the spindle ll, A pin 1S, -ixed in the sleeve, extends into the Space between two lugs 19, 19, provided on the .eide Wall of the chamber A ring Q0, provided with upward extending tong-noe 21, is slid on the top end of the Sleeve 12. The free ends of the said tongues hoor against accap 22', x'ed to the frame. The seid ring and tongues are adapted to support the sleeve 12 in a yielding mann-er, but n'my be dispensed with. I

In the inner eide of the vhood 2 is a groove or olmnnei 23 is provided', vWhichineloses r rather tightly the worm wheei 10, in order that a greet quantity of oil may accompany the Wheel" upward, when rotated in the direction indicated oy the arrow.

During the operation of the apparatus the worin wheel 10 rotates at e. rather greet velocity, about 500 to 600 revolutions per minute, in the direction indicated by the ar` row and Carries With it upward through the channel 23 a heavy current of oil from the receptacle provided in the bottom part of the frame, so that the said wheel acts like a wing Wheel. As the oil is thioWn out from the channel at the top pai-t of the pi'otectf ing hood, it is spread over the Whole chamber 3 like a drizzle; oil is caught by the neck bearing 14, from which it passes downward to the step bearingprovided iii the lower part of the sleeve 12 Anothei` part of the said spread oil is caught by the wall of the sleeve l2, which also passes doiviiiifaidfto the said step bearing. Also the Contact surfaces between the swell 15 and the shelf 16 are lubricated by the spread oil. The oil caught by the Wall of the chainber 3 passes into the pockets mentioned above and then `to the bearings of the Shafts- .6 and 7! fiom which it passes to the oil receptacle in the bottom part of the frame, so that the oil ci'iculates continuously.

Having now described my invention,

A part ofthe said what I claim as new and desire to secure by bination of a closed chamber provided in the iframe, a driving gearing located in the chamber, iiieans for supplying lubricating oil to the perpher f of a. number of wheels of the said gearing', a. sleeve located in the chamber, a ball joint connecting the sleeve with the frame, the said sleeve forming a step beaiiigaiid a neck bearing, e. spindle adapted for carrying a centrifugal drum and located in the said bearings, the Said neck beating having a free situation in the said chamber and being located iii the cuirent of oil coming from the said wheels7 so that its top art will receive the direct iinpact of the oil.

In Witness whereof7 I have hereunto signed my 'naine in the presence of two siib- Sciibiig Witnesses.
